Hello everyone,
I'm at a loss to find a way to send signals to other canvas items while
I have another already grabbed. Here's a simple example:
I've got three "dots" on the canvas and I want to connect lines in
between. So I click on one "dot" which starts a line draw, then
I gnome_canvas_item_set() new points for that line as I draw ....
But I am no other objects get signals (eg., ENTER_NOTIFY) while I have
the line grabbed ... which I must do in order to continue drawing the
line.
There's got to be a way around this besides checking all canvas items
manually.
Thanks,
DT
